We shouldn't be leading anything anyway. I used to think the U.S was the greatest country on earth…and then I grew up. We're actually pretty shit compared to the rest of the first world countries.
It’s just as naive to think that the US is particularly bad as a country compared to any other country as it is to think that it’s the best. The truth is that people aren’t perfect, and no country can claim to be perfect either. Wherever you look in society, you will find flaws. It’s childish to get petulant about it, much more mature to simply decide to be the better part of your nature and do your best to have a beneficial impact on the world.
